Neutral Edison Breaks Ground in Milwaukee


Neutral Edison, a 31-story residential tower that recently broke ground in Milwaukee, Wisconsin, is on track to become the tallest mass timber building in North America. Thornton Tomasetti is providing structural engineering services as the mass timber expert and mass timber special inspector, as well as delivering façade engineering, façade access consulting and Passive House (Phius) verification.
Developed by Madison-based Neutral, the 375-foot-tall tower was designed by Hartshorne Plunkard Architecture. When completed in 2027, Neutral Edison will surpass the current world’s tallest timber building, Ascent, for which Thornton Tomasetti also provided structural design, construction engineering and special inspection services.
We are proud to be part of the team making this historic achievement possible, while continuing to drive innovation in our hometown of Milwaukee.
Neutral Edison will feature 378 apartments, 7,200 square feet of retail space and various amenities, such as fitness and wellness clubs, a rooftop lounge, dog park and community garden. The project is pursuing both Phius and Living Building Challenge Core certifications and is expected to reduce embodied carbon by 54% and operational carbon by 45% compared to conventional construction.
